Abstract

The apparatus to process foodstuffs with a water enriched with ozone, by washing, has at least two reserves of an initial solution (41), a supply (22) of a gas mixture containing ozone, a station (23) where ozone is added to a fresh water supply and an injection system (25,L1-L3) to feed the water with ozone into each reserve. The injection system has at least two control units (27) to determine the vols. fed into the reserves. The dissolved ozone content in the water flow is equal to or greater than the highest ozone content in the reserves. A monitor system (46,47) registers the ozone content at each reserve to be passed to a data processing unit (26) for comparison of the ozone level at each reserve. Deviations are corrected by the feed controls (27), to maintain the required ozone content level, through command signals (28) from the data processing station (26). A buffer store (25) can be supplied with water containing ozone, with outlet lines (L1-L3) to the reserves (41), each with a flow control (27). At least one of the reserves has a secondary feed line (21b) of additional water as an independent feed, or into the ozone water supply downstream of the control point. The ozone water at the reserve is recirculated in its own circuit, including another reserve, or in a circuit containing the primary supply (21) and the ozone treatment station (23). A filter is in the recirculation for the water from the reserve and also for water with ozone, before it reaches the main supply point in the circuit. The system to apply ozone to the water can have a buffer store, for the ozone action, fed from the main supply and with outlet lines to the reserves through control points. The ozone treatment buffer has an inner porous diffuser, to deliver the processing gas, and a closed loop where ozone can be dissolved in the water flow. At least one of the reserves is fitted with an injection system, to deliver ozone into the stored water. An Independent claim is included for a water processing operation, where ozone is introduced into it. The water with ozone is held in reserves, and a water flow to the reserves is treated with ozone to be dissolved in it. Preferred Features: The water with ozone is passed to a buffer store, to be distributed to the reserves, with controlled feed flows. The water level is monitored at each reserve to determine the main feed of water containing ozone and a secondary feed.
